CELEBRITY BIG BROTHER housemates were left shocked as singer Ariana Grande paid her brother Frankie a visit in the house yesterday.

The housemates have been getting visits from their nearest and dearest and Ariana was Frankie's surprise… but, being the busy superstar that she is, she was unable to visit the Borehamwood bungalow in person.

However, she did make sure to record a video message for her older brother, which will be shown on tonight's episode.

Ariana moved Frankie to tears as she said: "I’m so proud of you, come home soon, oh, not too soon, win first."
